UNIVEST CORPORATION OF PENNSYLVANIA AND SUBSIDIARIES

Notes to the Condensed Unaudited Consolidated Financial Statements

Note 1. Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of Univest Corporation of Pennsylvania (the Corporation or Univest) and its wholly owned subsidiaries. The Corporation’s direct subsidiary is Univest Bank and Trust Co. (the Bank). All significant intercompany balances and transactions have been eliminated in consolidation. The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations for interim financial information. The accompanying unaudited consolidated financial statements reflect all adjustments which are of a normal recurring nature and are, in the opinion of management, necessary for a fair presentation of the financial statements for the interim periods presented. Certain prior period amounts have been reclassified to conform to the current-year presentation. Operating results for the three-month period ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ended December 31, 2018 or for any other period. It is suggested that these unaudited consolidated financial statements be read in conjunction with the audited financial statements and the notes thereto included in the registrant’s Annual Report on Form 10-K for the year ended December 31, 2017, which was filed with the SEC on March 1, 2018.

Use of Estimates

The preparation of the unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include fair value measurement of investment securities available-for-sale, reserve for loan and lease losses and purchase accounting.

Accounting Pronouncements Adopted in 2018

In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-02, "Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This ASUclarifies the accounting treatment of the reclassification of certain income tax effects within accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act. The Corporation elected to early adopt this guidance effective January 1, 2018 for all stranded tax effects resulting from tax reform and reclassified stranded tax effects, totaling $3.9 million, from accumulated other comprehensive income to retained earnings. The Corporation's policy for releasing income tax effects from accumulated other comprehensive income is to release such effects on an individual basis as each item is liquidated, sold or extinguished. See Note 10, "Accumulated Other Comprehensive (Loss) Income" for additional detail.

In March 2017, the FASB issued ASU No. 2017-07, "Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The amendments in this ASU require that an employer that sponsors defined benefit pension plans and other postretirement plans present the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. Other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The Corporation adopted this guidance effective January 1, 2018 with retrospective application for prior period presentation. Effective January 1, 2018, components of net benefit income other than the service cost component are presented in the Corporation's statement of income in other noninterest expense rather than in salaries, benefits and commission expense. Prior period components of net benefit income other than the service cost component were reclassed to other noninterest expense in the Corporation's statement of income.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." This ASU addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The ASU requires equity investments to be measured at fair value with changes in fair value recognized in net income. At December 31, 2017, the Corporation's equity portfolio had a carrying value of $1.1 million which included an unrealized net gain of $666 thousand. At December 31, 2017, $433 thousand was recorded in accumulated

7

other comprehensive income which represented the unrealized net gain, net of income taxes, based on the Corporation’s statutory tax rate as of December 31, 2017. The Corporation adopted this guidance effective January 1, 2018 with a cumulative-effect adjustment to the balance sheet as of January 1, 2018. The balance in accumulated other comprehensive income of $433 thousand was reclassified to retained earnings effective January 1, 2018. The carrying value of the equity securities, at January 1, 2018, did not change; however, any future increases or decreases in fair value is recorded as an increase or decrease to the carrying value and recognized in other noninterest income. During the three months ended March 31, 2018, the Corporation recognized a $4 thousand net loss on equity securities in other noninterest income.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)” and subsequent related updates. The Corporation adopted the guidance effective January 1, 2018 using the modified retrospective method though no adjustments were made to retained earnings as a result of the adoption. The Corporation provided expanded disclosures related to recognition of revenue from contracts with customers. See Note 14, "Revenue from Contracts with Customers."

Recent Accounting Pronouncements Yet to Be Adopted

In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." The amendments in this update expand and refine hedge accounting for both non-financial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. Additional hedging strategies permitted for hedge accounting include: hedges of contractually-specified price components of commodity purchases or sales, hedges of the benchmark rate component of the contractual coupon cash flows of fixed-rate assets or liabilities, hedges of the portion of a closed portfolio of prepayable assets not expected to prepay, and partial-term hedges of fixed-rate assets or liabilities. The ASU amends the presentation and disclosure requirements and changes how entities assess effectiveness. The ASU eliminates the requirement to separately measure and report hedge ineffectiveness and requires all items that affect earnings be presented in the same income statement line as the hedged items. After initial qualification, the new guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test, such as a regression analysis, if the entity can reasonably support an expectation of high effectiveness throughout the term of the hedge. An initial quantitative test to establish that the hedge relationship is highly effective is still required. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for public business entities, or January 1, 2019 for the Corporation. Early adoption is permitted, including an interim period. The amended presentation and disclosure guidance is required only prospectively. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements.

In March 2017, the FASB issued ASU No. 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” This ASU shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, or January 1, 2019 for the Corporation. Early adoption is permitted, including an interim period. This ASU is to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This ASU eliminates Step 2 of the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the new guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, or for the Corporation's goodwill impairment test in 2020. Early adoption is permitted for goodwill impairment tests with measurement dates after January 1, 2017. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU requires businesses and other organizations to measure the current expected credit losses (CECL) on financial assets, such as loans, net investments in leases, certain debt securities, bond insurance and other

8

receivables. The amendments affect entities holding financial assets and net investments in leases that are not accounted for at fair value through net income. Current GAAP requires an incurred loss methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. The amendments in this ASU replace the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonableness and supportable information to inform credit loss estimates. An entity should apply the amendments through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (modified-retrospective approach). Acquired credit impaired loans for which the guidance in Accounting Standards Codification (ASC) Topic 310-30 has been previously applied should prospectively apply the guidance in this ASU. A prospective transition approach is required for debt securities for which an other-than-temporary impairment has been recognized before the effective date. The ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those years for public business entities that are SEC filers, or January 1, 2020 for the Corporation. The Corporation is in the process of evaluating the impact of the adoption of this guidance on the Corporation's financial statements; however, it is anticipated that the allowance will increase upon adoption of CECL and that the increased allowance level will decrease shareholders' equity and regulatory capital and ratios.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" to revise the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases. Disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. The ASU is effective for the first interim period within annual periods beginning after December 15, 2018, or January 1, 2019, with early adoption permitted. The Corporation is in the process of evaluating the impact of the adoption of this guidance on the Corporation's financial statements; however, the adoption of this ASU will impact the balance sheet for the recording of assets and liabilities for operating leases; any initial or continued impact of the recording of assets will have a negative impact on all Corporation and Bank capital ratios under current regulatory guidance and possibly equity ratios.

Note 2. Earnings per Share

The Corporation uses the two-class method to calculate earnings per share as the unvested restricted stock issued under the Corporation's equity incentive plans are participating shares with nonforfeitable rights to dividends. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the number of weighted average shares outstanding during the period. The table also notes anti-dilutive options which are those options with weighted average exercise prices in excess of the weighted average market value for the periods presented.

The following table sets forth the computation of basic and diluted earnings per share:

N/A - Not applicable as a result of adoption of ASU 2016-01

Expected maturities may differ from contractual maturities because debt issuers may have the right to call or prepay obligations without call or prepayment penalties and mortgage-backed securities typically prepay at a rate faster than contractually due.

Securities with a carrying value of $362.5 million and $345.1 million at March 31, 2018 and December 31, 2017, respectively, were pledged to secure public deposits and other contractual obligations. In addition, securities of $296 thousand and $1.8 million were pledged to secure credit derivatives and interest rate swaps at March 31, 2018 and December 31, 2017, respectively. See Note 11, "Derivative Instruments and Hedging Activities" for additional information.

The following table presents information related to sales of securities available-for-sale during the three months ended March 31, 2018 and 2017:

At March 31, 2018 and December 31, 2017, there were no investments in any single non-federal issuer representing more than 10% of shareholders’ equity.

The following table shows the fair value of securities that were in an unrealized loss position at March 31, 2018 and December 31, 2017 by the length of time those securities were in a continuous loss position. For the investment securities in an unrealized loss position, the Corporation has concluded, based on its analysis, that the unrealized losses are primarily caused by the movement of interest rates and current market conditions. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the par value of the investment. It is more likely than not that the Corporation will not be required to sell the investments before a recovery of carrying value.

At March 31, 2018, gross unrealized losses for securities in an unrealized loss position for twelve months or longer, totaled $12.0 million. Four federal agency bonds, thirteen investment grade corporate bonds, 105 federal agency residential mortgage securities, and seven investment grade municipal bonds had respective unrealized loss positions of $105 thousand, $6.7 million, $5.2 million and $51 thousand, respectively. The fair value of these 129 securities fluctuate with changes in market conditions which for these underlying securities is primarily due to changes in the interest rate environment. The Corporation does not intend to sell the securities in an unrealized loss position and is unlikely to be required to sell these securities before a recovery of fair value, which may be maturity. Upon review of the attributes of the individual securities, the Corporation concluded these securities were not other-than-temporarily impaired. The Corporation did not recognize any other-than-temporary impairment charges on debt securities for the three months ended March 31, 2018 and 2017.

In conjunction with the adoption of ASU 2016-01, the Corporation recognized a $4 thousand net loss on equity securities during the three months ended March 31, 2018 in other noninterest income and the net unrealized loss on equity securities held at March 31, 2018 was $4 thousand. See Note 1, "Summary of Significant Accounting Policies - Accounting Pronouncements Adopted in 2018" for additional information.

Accruing troubled debt restructuring loans of $11.4 million at December 31, 2017 includes balances of $10.3 million related to one borrower which were classified as troubled debt restructurings as the related loans were granted amortization period extensions. These troubled debt restructured loans were returned to performing status during the first quarter of 2018 as the borrower was in compliance with the modified terms of the restructurings for the required time period. At March 31, 2018, commercial real estate nonaccrual loans and leases includes a $12.3 million loan that was placed on nonaccrual status during the current quarter. A specific reserve of $656 thousand was recorded for this loan as of March 31, 2018.

Credit Quality Indicators

The following tables present by class, the recorded investment in loans and leases held for investment by credit quality indicator at March 31, 2018 and December 31, 2017.

Loans with a relationship balance of less than $1 million are reviewed on a performance basis, with the primary monitored metrics being delinquency (60 days or more past due) and revolving stagnancy. Loans with relationships greater than $1 million are reviewed at least annually.  Loan relationships exceeding $15 million or classified as special mention or substandard are reviewed at least quarterly, or more frequently based on management’s discretion. 

1. Cash Secured—No credit risk

2. Fully Secured—Negligible credit risk

3. Strong—Minimal credit risk

4. Satisfactory—Nominal credit risk

5. Acceptable—Moderate credit risk

6. Pre-Watch—Marginal, but stable credit risk

7. Special Mention—Potential weakness

8. Substandard—Well-defined weakness

9. Doubtful—Collection in-full improbable

The Corporation records a provision for loan loss for the acquired non-impaired loans only when additional deterioration of the portfolio is identified over the projections utilized in the initial fair value analysis. After the acquisition measurement period, the present value of any decreases in expected cash flows of acquired credit impaired loans will generally result in an impairment charge recorded as a provision for loan loss, resulting in an increase to the allowance.

Impaired Loans (excludes Lease Financings)

The following presents, by class of loans, the recorded investment and unpaid principal balance of impaired loans, the amounts of the impaired loans for which there is not a reserve for credit losses and the amounts for which there is a reserve for credit losses at March 31, 2018 and December 31, 2017.

Impaired loans include nonaccrual loans, accruing troubled debt restructured loans and other accruing impaired loans for which it is probable that not all principal and interest payments due will be collectible in accordance with the original contractual terms. These loans are individually measured to determine the amount of potential impairment. The loans are reviewed for impairment based on the fair value of the collateral for collateral dependent loans and for certain loans based on discounted cash flows using the loans’ initial effective interest rates. Impaired loans include other accruing impaired loans of $3.3 million and $4.1 million at March 31, 2018 and December 31, 2017, respectively. Specific reserves on other accruing impaired loans were $28 thousand and $99 thousand at March 31, 2018 and December 31, 2017, respectively.

21

The following presents by class of loans, the average recorded investment in impaired loans and an analysis of interest on impaired loans. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. Therefore, interest income on accruing impaired loans is recognized using the accrual method.

Impaired Leases

The Corporation had impaired leases of $1.3 million at March 31, 2018 and December 31, 2017 with no related reserves. See discussion in Reserve for Loan and Lease Losses and Recorded Investment in Loans and Leases.

Troubled Debt Restructured Loans

There were no loans restructured during the three months ended March 31, 2018 and March 31, 2017.

The Corporation grants concessions to existing borrowers primarily related to extensions of interest-only payment periods and an occasional payment modification. These modifications typically are for up to one year. The goal when restructuring a credit is to establish a reasonable period of time to provide cash flow relief to customers experiencing cash flow difficulties. Accruing troubled debt restructured loans are primarily comprised of loans on which interest is being accrued under the restructured terms, and the loans are current or less than ninety days past due.

22

The following presents, by class of loans, information regarding accruing and nonaccrual troubled debt restructured loans, for which there were payment defaults within twelve months of the restructuring date:

The Corporation has originated mortgage servicing rights, which are included in other intangible assets on the consolidated balance sheets. Mortgage servicing rights are amortized in proportion to, and over the period of, estimated net servicing income on a basis similar to the interest method and an accelerated amortization method for loan payoffs. Mortgage servicing rights are subject to impairment testing on a quarterly basis. The aggregate fair value of these rights was $11.2 million at March 31, 2018 and $10.0 million at December 31, 2017. The fair value of mortgage servicing rights was determined using a discount rate of 10.0% at March 31, 2018 and December 31, 2017. The Corporation also records servicing rights on small business administration (SBA) loans. The value of these servicing rights was $20 thousand and $21 thousand at March 31, 2018 and December 31, 2017, respectively.

Note 8. Retirement Plans and Other Postretirement Benefits

Substantially all employees who were hired before December 8, 2009 are covered by a noncontributory retirement plan. Employees hired on or after December 8, 2009 are not eligible to participate in the noncontributory retirement plan. The Corporation also provides supplemental executive retirement benefits to certain former executives, a portion of which is in excess of limits imposed on qualified plans by federal tax law; these plans are non-qualified benefit plans. These non-qualified benefit plans are not offered to new participants; all current participants are now retired. Information on these plans are aggregated and reported under “Retirement Plans” within this footnote.

The Corporation also provides certain postretirement healthcare and life insurance benefits for retired employees. Information on these benefits is reported under “Other Postretirement Benefits” within this footnote.

The Corporation sponsors a Supplemental Non-Qualified Pension Plan, which was established in 1981 prior to the existence of a 401(k) deferred salary savings plan, employee stock purchase plan and long-term incentive plans and therefore is not offered to new participants; all current participants are now retired.

Note 11. Derivative Instruments and Hedging Activities

Interest Rate Swaps

The Corporation may use interest rate swap agreements to modify interest rate characteristics from variable to fixed or fixed to variable in order to reduce the impact of interest rate changes on future net interest income. Recorded amounts related to interest-rate swaps are included in other assets or liabilities. The Corporation’s credit exposure on interest rate swaps includes fair value and any collateral that is held by a third party. Changes in the fair value of derivative instruments designated as hedges of future cash flows are recognized in accumulated other comprehensive income until the underlying forecasted transactions occur, at which time the deferred gains and losses are recognized in earnings. For a qualifying fair value hedge, the gain or loss on the hedging instrument is recognized in earnings, and the change in fair value of the hedge item, to the extent attributable to the hedged risk, adjusts the carrying amount of the hedge item and is recognized in earnings.

In 2014, the Corporation entered into an amortizing interest rate swap classified as a cash flow hedge with a notional amount of $20.0 million to hedge a portion of the debt financing of a pool of 10-year maturity fixed rate loans with balances totaling $29.1 million, at time of the hedge, that were originated in 2013. A brokered money market demand account with a balance exceeding the amortizing interest rate swap balance is being used for the cash flow hedge. Under the terms of the swap agreement, the Corporation pays a fixed rate of 2.10% and receives a floating rate of one-monthLIBOR. The swap matures in November 2022. The Corporation performed an assessment of the hedge for effectiveness at the inception of the hedge and on a recurring basis to determine that the derivative has been and is expected to continue to be highly effective in offsetting changes in cash flows of the hedged item. The Corporation expects that there will be no ineffectiveness over the life of the interest rate swap. At March 31, 2018, there is no gain or loss recorded in accumulated other comprehensive loss that is expected to be reclassified into earnings during the next twelve months. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to March 31, 2018. At March 31, 2018, the notional amount of the interest rate swap was $17.6 million, with a positive fair value of $294 thousand.

The Corporation has an interest rate swap classified as a fair value hedge with a current notional amount of $1.4 million to hedge a 10-year fixed rate loan that is earning interest at 5.83%. The Corporation pays a fixed rate of 5.83% and receives a floating rate based on the one-month LIBOR plus 350 basis points. The swap matures in October 2021. The difference between changes in the fair values of the interest rate swap agreement and the hedged loan represents hedge ineffectiveness and is recorded in other noninterest income in the consolidated statements of operations.

The Corporation has an interest rate swap with a current notional amount of $497 thousand, for a 15-year fixed rate loan that is earning interest at 7.43%. The Corporation pays a fixed rate of 7.43% and receives a floating rate based on the one-month LIBOR plus 224 basis points. The swap matures in April 2022. The interest rate swap is carried at fair value in accordance with

29

FASB ASC 815 "Derivatives and Hedging." The loan is carried at fair value under the fair value option as permitted by FASB ASC 825 "Financial Instruments."

Credit Derivatives

The Corporation has agreements with third-party financial institutions whereby the third-party financial institution enters into interest rate derivative contracts and foreign currency swap contracts with loan customers referred to them by the Corporation. By the terms of the agreements, the third-party financial institution has recourse to the Corporation for any exposure created under each swap contract in the event the customer defaults on the swap agreement and the agreement is in a paying position to the third-party financial institution. These transactions represent credit derivatives and are a customary arrangement that allows the Corporation to provide access to interest rate and foreign currency swap transactions for customers without creating the swap. The Corporation records the fair value of credit derivatives in other liabilities on the consolidated balance sheets. The Corporation recognizes changes in the fair value of credit derivatives, net of any fees received, in other noninterest income in the consolidated statements of income.

At March 31, 2018, the Corporation has fifteen variable-rate to fixed-rate interest rate swap transactions between the third-party financial institution and customers with a current notional amount of $75.0 million, and remaining maturities ranging from one to 10 years. At March 31, 2018, the fair value of the swaps to the customers was a liability of $31 thousand and all swaps were in paying positions to the third-party financial institution.

At March 31, 2018, there were no material foreign currency swap transactions between the third-party institution and loan customers.

The maximum potential payments by the Corporation to the third-party financial institution under these credit derivatives are not estimable as they are contingent on future interest rates and exchange rates, and the agreement does not provide for a limitation of the maximum potential payment amount.

Mortgage Banking Derivatives

Derivative loan commitments represent agreements for delayed delivery of financial instruments in which the buyer agrees to purchase and the seller agrees to deliver, at a specified future date, a specified instrument at a specified price or yield. The Corporation’s derivative loan commitments are commitments to sell loans secured by 1-to 4-family residential properties whose predominant risk characteristic is interest rate risk. The fair values of these derivative loan commitments are based upon the estimated amount the Corporation would receive or pay to terminate the contracts or agreements, taking into account current interest rates and, when appropriate, the current creditworthiness of the counterparties.

Derivatives Tables

The following table presents the notional amounts and fair values of derivatives designated as hedging instruments recorded on the consolidated balance sheets at March 31, 2018 and December 31, 2017.

Note 12. Fair Value Disclosures

Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The Corporation determines the fair value of financial instruments based on the fair value hierarchy. The Corporation maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Corporation. Unobservable inputs are inputs that reflect the Corporation’s assumptions that market participants would use in pricing the asset or liability based on the best information available in the circumstances, including assumptions about risk. Three levels of inputs are used to measure fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement. Transfers between levels are recognized at the end of the reporting period.

Level 1: Valuations are based on quoted prices in active markets for identical assets or liabilities that the Corporation can access at the measurement date. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment.

Level 2: Valuations are based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3: Valuations are based on inputs that are unobservable and significant to the overall fair value measurement. Assets and liabilities utilizing Level 3 inputs include: financial instruments whose value is determined using pricing models, discounted cash-flow methodologies, or similar techniques, as well as instruments for which the fair value calculation requires significant management judgment or estimation.

Following is a description of the valuation methodologies used for instruments measured at fair value on a recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy.

Investment Securities

Where quoted prices are available in an active market for identical instruments, investment securities are classified within Level 1 of the valuation hierarchy. Level 1 investment securities include U.S. Treasury securities, most equity securities and money market mutual funds. Mutual funds are registered investment companies which are valued at net asset value of shares on a market exchange at the end of each trading day. Level 2 of the valuation hierarchy includes securities issued by U.S. Government sponsored enterprises, mortgage-backed securities, collateralized mortgage obligations, corporate and municipal bonds and certain equity securities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. In cases where there is limited activity or less transparency around inputs to the valuation, investment securities are classified within Level 3 of the valuation hierarchy.

Fair values for securities are determined using independent pricing services and market-participating brokers. The Corporation’s independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information for structured securities, cash flow and, when available, loan performance data. Because many fixed income securities do not trade on a daily basis, the pricing service’s evaluated pricing applications apply information as applicable through processes, such as benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations. If at any time, the pricing service determines that it does not have sufficient verifiable information to value a particular security, the Corporation will utilize valuations from another pricing service. Management has a sufficient understanding of the third party service’s valuation models, assumptions and inputs used in determining the fair value of securities to enable management to maintain an appropriate system of internal control.

Certain corporate bonds owned by the Corporation are classified as Level 3 as they are not traded in active markets. The fair value of each bond is estimated by benchmarking similar transactions of structure, yield and credit which are owned by the Corporation and are actively traded in the market.

On a quarterly basis, the Corporation reviews changes, as submitted by the pricing service, in the market value of its security portfolio. Individual changes in valuations are reviewed for consistency with general interest rate movements and any known credit concerns for specific securities. If, upon the Corporation’s review or in comparing with another service, a material difference between pricing evaluations were to exist, the Corporation may submit an inquiry to the current pricing service regarding the data used to determine the valuation of a particular security. If the Corporation determines there is market information that would support a different valuation than from the current pricing service’s evaluation, the Corporation may utilize and change the security's valuation. There were no material differences in valuations noted at March 31, 2018.

32

Derivative Financial Instruments

The fair values of derivative financial instruments are based upon the estimated amount the Corporation would receive or pay to terminate the contracts or agreements, taking into account current interest rates and, when appropriate, the current creditworthiness of the counterparties. Interest rate swaps and mortgage banking derivative financial instruments are classified within Level 2 of the valuation hierarchy. Credit derivatives are valued based on credit worthiness of the underlying borrower which is a significant unobservable input and therefore classified in Level 3 of the valuation hierarchy.

Two commercial loans associated with interest rate swaps are classified in Level 3 of the valuation hierarchy since lending credit risk is not an observable input for these loans. The unrealized gain on the two loans was $27 thousand at March 31, 2018.

Contingent Consideration Liability

The Corporation estimates the fair value of the contingent consideration liability by using a discounted cash flow model of future contingent payments based on projected revenue related to the acquired business. The estimated fair value of the contingent consideration liability is reviewed on a quarterly basis and any valuation adjustments resulting from a change of estimated future contingent payments based on projected revenue of the acquired business affecting the contingent consideration liability will be recorded through noninterest expense. Due to the significant unobservable input related to the projected revenue, the contingent consideration liability is classified within Level 3 of the valuation hierarchy. An increase in the projected revenue may result in a higher fair value of the contingent consideration liability. Alternatively, a decrease in the projected revenue may result in a lower estimated fair value of the contingent consideration liability.

The following table presents the assets and liabilities measured at fair value on a recurring basis at March 31, 2018 and December 31, 2017, classified using the fair value hierarchy:

The following valuation methods and assumptions were used by the Corporation in estimating the fair value for financial instruments measured at fair value on a non-recurring basis and financial instruments not measured at fair value on a recurring or non-recurring basis in the Corporation’s consolidated balance sheets but for which the fair value is required to be disclosed:

Cash and short-term interest-earning assets: The carrying amounts reported in the balance sheet for cash and due from banks, interest-earning deposits with other banks, federal funds sold and other short-term investments is their stated value. Cash and short-term interest-earning assets are classified within Level 1 in the fair value hierarchy.

Held-to-maturity securities: Fair values for the held-to-maturity investment securities are estimated by using pricing models or quoted prices of securities with similar characteristics and are classified in Level 2 in the fair value hierarchy.

Federal Home Loan Bank, Federal Reserve Bank and other stock: It is not practical to determine the fair values of Federal Home Loan Bank, Federal Reserve Bank and other stock, due to restrictions placed on their transferability.

Loans held for sale: The fair value of the Corporation’s mortgage loans held for sale are generally determined using a pricing model based on current market information obtained from external sources, including interest rates, bids or indications provided by market participants on specific loans that are actively marketed for sale. These loans are primarily residential mortgage loans and are generally classified in Level 2 due to the observable pricing data. Loans held for sale are carried at the lower of cost or estimated fair value. There were no valuation adjustments for loans held for sale at March 31, 2018 and December 31, 2017.

Loans and leases held for investment: As of March 31, 2018, the fair values for loans and leases held for investment are estimated using discounted cash flow analyses, using a discount rate based on current interest rates at which similar loans with similar terms would be made to borrowers, adjusted as appropriate to consider credit, liquidity and marketability factors to arrive at a fair value that represents the Corporation's exit price at which these instruments would be sold or transferred. As of December 31, 2017, the fair values for loans and leases held for investment were estimated using discounted cash flow analyses, using a discount rate based on current interest rates at which similar loans with similar terms would be made to borrowers and include components for credit risk, operating expense and embedded prepayment options. An overall valuation adjustment was made for specific credit risks in addition to general portfolio risk and is significant to the valuation.Loans and leases are classified within Level 3 in the fair value hierarchy.

37

Impaired loans and leases held for investment: For impaired loans and leases, the Corporation uses a variety of techniques to measure fair value, such as using the current appraised value of the collateral, agreements of sale, discounting the contractual cash flows, and analyzing market data that the Corporation may adjust due to specific characteristics of the loan/lease or collateral. At March 31, 2018, impaired loans held for investment had a carrying amount of $40.6 million with a valuation allowance of $732 thousand. At December 31, 2017, impaired loans held for investment had a carrying amount of $28.5 million with a valuation allowance of $131 thousand. The Corporation had impaired leases of $1.3 million with no reserve at March 31, 2018 and December 31, 2017.

Servicing rights: The Corporation estimates the fair value of mortgage servicing rights using discounted cash flow models that calculate the present value of estimated future net servicing income. The model uses readily available prepayment speed assumptions for the interest rates of the portfolios serviced. Mortgage servicing rights are classified within Level 3 in the fair value hierarchy based upon management's assessment of the inputs. The Corporation reviews the mortgage servicing rights portfolio on a quarterly basis for impairment and the mortgage servicing rights are carried at the lower of amortized cost or estimated fair value. The Corporation also records servicing rights on SBA loans. At March 31, 2018 and December 31, 2017, servicing rights had a carrying amount of $6.6 million with no valuation allowance.

Goodwill and other identifiable assets: Certain non-financial assets subject to measurement at fair value on a non-recurring basis include goodwill and other identifiable intangible assets. During the three months ended March 31, 2018, there were no triggering events that required valuation of goodwill and other identifiable intangible assets.

Other real estate owned: The fair value of other real estate owned (OREO) is originally estimated based upon the appraised value less estimated costs to sell. The fair value less cost to sell becomes the "original cost" of the OREO asset. Subsequently, OREO is reported as the lower of the original cost and the current the fair value less cost to sell. Capital improvement expenses associated with the construction or repair of the property are capitalized as part of the cost of the OREO asset; however, the capitalized expenses may not increase the OREO asset's recorded value to an amount greater than the asset's fair value after improvements and less cost to sell. At March 31, 2018 and December 31, 2017, OREO had a carrying amount of $1.8 million. New appraisals are generally obtained on an annual basis if an agreement of sale does not exist. Other real estate owned is classified within Level 3 of the valuation hierarchy due to the unique characteristics of the collateral for each loan.

Deposit liabilities: The fair values for demand and savings accounts, with no stated maturities, is the amount payable on demand at the reporting date (carrying value) and are classified within Level 1 in the fair value hierarchy. The fair values for time deposits with fixed maturities are estimated by discounting the final maturity using interest rates currently offered for deposits with similar remaining maturities. Time deposits are classified within Level 2 in the fair value hierarchy.

Short-term borrowings: The fair value of short-term borrowings are estimated using current market rates for similar borrowings and are classified within Level 2 in the fair value hierarchy.

Long-term debt: The fair value of long-term debt is estimated by using discounted cash flow analysis, based on current market rates for debt with similar terms and remaining maturities. Long-term debt is classified within Level 2 in the fair value hierarchy.

Subordinated notes: The fair value of the subordinated notes are estimated by discounting the principal balance using the treasury yield curve for the term to the call date as the Corporation has the option to call the subordinated notes. The subordinated notes are classified within Level 2 in the fair value hierarchy.

Off-balance-sheet instruments: Fair values for the Corporation’s off-balance-sheet instruments are based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing and are classified within Level 2 in the fair value hierarchy.

Note 13. Segment Reporting

At March 31, 2018, the Corporation has three reportable business segments: Banking, Wealth Management and Insurance. The Corporation determines the segments based primarily upon product and service offerings, through the types of income generated and the regulatory environment. This is strategically how the Corporation operates and has positioned itself in the marketplace. Accordingly, significant operating decisions are based upon analysis of each of these segments. The parent holding company and intercompany eliminations are included in the "Other" segment.

The Corporation's Banking segment consists of commercial, consumer and mortgage banking as well as lease financing. The Wealth Management segment consists of investment advisory services, retirement plan services, trust, municipal pension services

38

and broker/dealer services. The Insurance segment consists of commercial lines, personal lines, benefits and human resources consulting.

Each segment generates revenue from a variety of products and services it provides. Examples of products and services provided for each reportable segment are indicated below.

Ÿ	The Banking segment provides financial services to consumer and commercial customers and governmental units. These services include a full range of banking services such as deposit taking, loan origination and servicing, mortgage banking, other general banking services and equipment lease financing.
Ÿ	The Wealth Management segment offers trust and investment advisory services, guardian and custodian of employee benefits and other trust and brokerage services, as well as a registered investment advisory managing private investment accounts for both individuals and institutions.
Ÿ	The Insurance segment includes a full-service insurance brokerage agency offering commercial property and casualty insurance, group life and health coverage, employee benefit solutions, personal insurance lines and human resources consulting.

The following table provides total assets by reportable business segment as of the dates indicated.

Note 14. Revenue from Contracts with Customers

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)” and subsequent related updates. The Corporation adopted the guidance effective January 1, 2018 using the modified retrospective method though no adjustments were made to retained earnings as a result of the adoption. The Corporation’s revenue is the sum of net interest income and noninterest income. Revenues are recognized when obligations under the terms of contracts with customers are satisfied, including the transfer of control of the promised goods or services to customers, in an amount that reflects the consideration the Corporation expects to be entitled to in exchange for those goods or services. The Corporation provides services to customers which have related performance obligations that are completed to recognize revenue. The Corporation's revenues are generally recognized either immediately upon the completion of the services or over time as the services are performed. Any services performed over time generally require services to be rendered each period and therefore progress in completing these services is measured based upon the passage of time.

The following tables disaggregate the Corporation's revenue by major source for the three months ended March 31, 2018 and 2017.

(2) Other service fee income and other income include certain items that are in scope and certain items that are out of scope of the standard and are described further in the following paragraphs.

Banking Segment

The Banking segment provides financial services to consumer and commercial customers and governmental units. These services include a full range of banking services such as deposit taking, loan origination and servicing, mortgage banking, other general banking services and equipment lease financing.

Service charges on deposit accounts are generally earned on depository accounts for commercial and consumer customers and primarily includes fees for account services, overdraft services, and cash management services for commercial customers. Account services include fees for event-driven services such as ATM transactions and fees for periodic account maintenance activities. Cash management services for commercial customers include fees for event-driven services such as lockbox processing and line sweep services and fees for periodic account maintenance activities. The Corporation's obligation for event-driven services is satisfied at the time of the event when the service is delivered, while the obligation for periodic services is satisfied over the course of each month. Obligations for overdraft services is satisfied at the time of the overdraft.

Other service fee income is earned from commercial and consumer customers and primarily includes credit and debit card interchange and merchant revenues, mortgage servicing income, which is out of scope of the standard, and other deposit related service fee income such as wire transfers, check services and safe deposit boxes. Interchange and merchant revenues are recognized concurrently with the delivery of services on a monthly basis.

The obligation for event-driven services is satisfied at the time of the event when the service is delivered, while the obligation for periodic services is satisfied over the course of each month.

Other income primarilyincludes net gains or losses from the sales of loans and leases, net gains or losses from the sales or disposition of fixed assets and net gains or losses on interest rate swaps, all of which are out of scope of the standard, and net gains or losses on sales and write-downs of other real estate owned. Net gains or losses on sales of other real estate owned are recognized at the point in time in which control of the other real estate owned is transferred.

Wealth Management Segment

The wealth management segment offers trust and investment advisory services, guardian and custodian of employee benefits and other trust and brokerage services, as well as a registered investment advisory managing private investment accounts for both individuals and institutions.

Obligations for trust and other related services are generally satisfied over time but may be satisfied at points in time for certain activities that are transactional in nature and obligations for investment management services are generally performed over time. Fees for trust fee income are typically based on a tiered scale relative to the market value of assets under management and are recognized in conjunction with the delivery of services.

Investment advisory commission and fee income include fees for financial planning, guardian and custodian of employee benefits, investment advisory, and brokerage services. Obligations for financial planning, guardian and custodian of employee benefits, and investment advisory services are generally satisfied over time and fees, typically based on a tiered scale relative to the market value of assets under management are recognized in conjunction with the delivery of services.

Insurance Segment

The insurance segment includes a full-service insurance brokerage agency offering commercial property and casualty insurance, group life and health coverage, employee benefit solutions, personal insurance lines and human resources consulting.

Insurance commission and fee income is derived primarily from commissions from the sale of insurance policies, which are generally calculated as a percentage of the policy premium, and contingent income, which is calculated based on the performance of the policies held by each carrier. Obligations for the sale of insurance policies are generally satisfied at the point in time which the policy is executed and are recognized at the point in time in which the amounts are knownand collection is reasonably assured. Obligations for contingent income are generally satisfied over time and are recognized at the point in time in which the amounts are known and collection is reasonably assured.

Other service fee income is earned from human resources consulting services. These obligations are generally satisfied over time and are recognized on a periodic basis.

Note 15. Restructuring Charges

During January 2018, the Corporation announced the closure of two owned financial centers and one leased financial center and reduced staff associated with these financial centers, resulting in accruing a loss of $571 thousand related to the Banking business segment. These financial centers were closed in April 2018. The remaining accrued restructuring expense at January 1, 2018 of $23 thousand relates to 2016 restructuring charges.

A roll-forward of the remaining accrued restructuring expense for the three months ended March 31, 2018 is as follows:

(Dollars in thousands)	Severance expenses			Write-downs and retirements of fixed assets		Lease cancellations			Total

Results of Operations

Net Interest Income

Net interest income is the difference between interest earned on loans and leases, investments and other interest-earning assets and interest paid on deposits and other interest-bearing liabilities. Net interest income is the principal source of the Corporation’s revenue. Table 1 presents a summary of the Corporation’s average balances, tax-equivalent interest income and interest expense and the tax-equivalent yields earned on average assets, and the cost of average liabilities, and shareholders’ equity on a tax-equivalent basis for the three months ended March 31, 2018 and 2017. The tax-equivalent net interest margin is tax-equivalent net interest income as a percentage of average interest-earning assets. The tax-equivalent net interest spread represents the weighted average tax-equivalent yield on interest-earning assets less the weighted average cost of interest-bearing liabilities. The effect of net interest free funding sources represents the effect on the net interest margin of net funding provided by noninterest-earning assets, noninterest-bearing liabilities and shareholders’ equity. Table 2 analyzes the changes in the tax-equivalent net interest income for the periods broken down by their rate and volume components.

Table 1, Table 2, and the interest income and net interest income analysis contain tax-equivalent financial information and measures determined by methods other than in accordance with U.S. GAAP. The management of the Corporation uses this non-GAAP financial information and measures in its analysis of the Corporation's performance. This financial information and measures should not be considered a substitute for GAAP basis financial information or measures nor should they be viewed as a substitute for operating results determined in accordance with GAAP. Management believes the presentation of the non-GAAP financial information and measures provide useful information that is essential to a proper understanding of the financial results of the Corporation.

The statutory federal tax rate utilized in the respective tables and analyses was 21% for the three months ended March 31, 2018 and was 35% for the three months ended March 31, 2017.

Three months ended March 31, 2018 versus 2017

Reported net interest income for the three months ended March 31, 2018 was $37.3 million, an increase of $3.0 million, or 8.7%, compared to the same period in 2017. Net interest income on a tax-equivalent basis for the three months ended March 31, 2018 was $37.9 million, an increase of $2.3 million, or 6.3%, compared to the same period in 2017. The increase in reported and tax-equivalent net interest income was primarily due to the growth in average loans of 9.9%, and a interest free funding through a combination of growth in average noninterest-bearing deposits of 9.9% and average equity of 19.0%, during the last year.

The net interest margin on a tax-equivalent basis for the first quarter of 2018 was 3.72%, compared to 3.80% for the first quarter of 2017. The favorable impact of purchase accounting accretion was 2 basis points ($146 thousand) for the three months ended March 31, 2018 compared to eight basis points ($764 thousand) for the three months ended March 31, 2017.

Interest Income

Three months ended March 31, 2018 versus 2017

Interest income on a tax-equivalent basis for the three months ended March 31, 2018 was $44.2 million, an increase of $4.4 million, or 11.1% from the same period in 2017. The increase in interest income (tax-equivalent) for the three months ended March 31, 2018 was primarily due to organic loan growth in commercial real estate, commercial business and residential real estate loans. In addition, loan yields increased as the Federal Reserve increased interest rates a total of 100 basis points in 2017 and the first quarter of 2018. Purchase accounting accretion had no impact on the yield on interest-earning assets for the three months ended March 31, 2018 compared to a favorable impact of two basis points ($149 thousand) for the same period in the prior year.

Interest Expense

Three months ended March 31, 2018 versus 2017

Interest expense for the three months ended March 31, 2018 was $6.3 million, an increase of $2.1 million, or 52.2% from the same period in 2017. The increase in interest expense for the three months ended March 31, 2018 was primarily due to higher deposit and borrowing costs which were impacted by the Federal Reserve interest rate increases in 2017 and the first quarter of 2018. The favorable impact of purchase accounting accretion on interest-bearing liabilities was three basis points ($186 thousand) for the three months ended March 31, 2018 compared to a favorable impact of nine basis points ($615 thousand) for the same period in the prior year.

Provision for Loan and Lease Losses

The provision for loan and lease losses for the three months ended March 31, 2018 was $2.1 million compared to $2.4 million for the same period in 2017. The level of provision for loan and lease losses is based on growth in the originated loan portfolio, changes in specific reserves for impaired loans and net loan charge-offs. During the three months ended March 31, 2018, a specific reserve in the amount of $656 thousand was provided for one $12.3 million nonaccrual commercial real estate loan. Net loan and lease charge-offs were $198 thousand for the three months ended March 31, 2018 compared to $416 thousand for the same period in the prior year.

Three months ended March 31, 2018 versus 2017

Noninterest income for the three months ended March 31, 2018 was $15.6 million, an increase of $612 thousand, or 4.1%, from the three months ended March 31, 2017. Investment advisory commission and fee income increased $502 thousand, or 15.8%, for the three months ended March 31, 2018 primarily due to new customer relationships and favorable market performance during 2017. Insurance commission and fee income increased $478 thousand, or 10.8%, for the three months ended March 31, 2018, primarily due to an increase in contingent commission income of $422 thousand, which was $1.4 million for the three months ended March 31, 2018 compared to $963 thousand for the three months ended March 31, 2017.

These increases were partially offset by a decrease in the net gain on mortgage banking of $397 thousand, or 35.7%, for the three months ended March 31, 2018, primarily due to a decrease in mortgage volume due to a shortage of housing supply and the extended winter weather in March 2018. In addition, BOLI income decreased $114 thousand, or 14.6% for the three months ended March 31, 2018, primarily due to a decrease in value of the Corporation's non-qualified annuity portfolio, which is subject to equity market volatility. Other income decreased $207 thousand for the three months ended March 31, 2018, mainly due to a decrease in swap fee income of $70 thousand and a net gain on sale of other real estate owned of $114 thousand during the three months ended March 31, 2017.

Three months ended March 31, 2018 versus 2017

Noninterest expense for the three months ended March 31, 2018 was $35.1 million, an increase of $3.1 million, or 9.7%, from the same period in the prior year. Restructuring costs related to financial center closures and staffing rationalization were $571 thousand for the three months ended March 31, 2018. There were no restructuring costs during the three months ended March 31, 2017.

Salaries, benefits and commissions increased $1.9 million for the three months ended March 31, 2018, primarily attributable to additional staff hired to support revenue generation across all business lines, expansion of the Bank's financial center footprint in Lancaster County and the Lehigh Valley and annual merit increases. Data processing expense increased $174 thousand for the three months ended March 31, 2018 primarily due to increased investments in customer relationship management software, internal infrastructure improvements and outsourced data processing solutions. Other expense increased $358 thousand for the three months ended March 31, 2018 primarily due to increases in deferred director stock expense and loan processing expense.

Tax Provision

The provision for income taxes for the three months ended March 31, 2018 and 2017 was $2.8 million and $3.9 million, at effective rates of 18.0% and 26.5%, respectively. As previously discussed, the Corporation's statutory federal tax rate was reduced to 21% effective January 1, 2018 in accordance with the TCJA. The Corporation's effective income tax rate for the three months ended March 31, 2018 was impacted by discrete tax benefits related to vesting of restricted stock and exercise of stock options

49

totaling $118 thousand. Excluding these discrete items, the effective tax rate was 18.8% for the three months ended March 31, 2018, which reflects the impact of the Corporation's level of tax-exempt income for the period relative to the overall level of taxable income.

Investment Securities

Total investments securities at March 31, 2018increased$8.2 million from December 31, 2017. Purchases of $38.3 million were partially off-set by maturities and pay-downs of $18.2 million, calls of $4.0 million, sales of $1.0 million and decreases in the fair value of available-for-sale investment securities of $6.3 million which was due to increased interest rates during the quarter.

Federal Home Loan Bank, Federal Reserve Bank and other stock, at cost

The Bank is a member of the FHLB, and as such, is required to hold FHLB stock as a condition of membership as determined by the FHLB. The Bank is required to hold additional stock in the FHLB in relation to the level of outstanding borrowings. The Bank held FHLB stock of $18.1 million and $12.5 million at March 31, 2018 and December 31, 2017, respectively. FHLB stock increased$5.6 million mainly due to purchase requirements related to the increase in FHLB borrowings during the quarter.

The Bank held $14.6 million in Federal Reserve Bank stock as required by the Federal Reserve Bank at March 31, 2018 and December 31, 2017.

Loans and Leases

Gross loans and leases held for investment grew $69.8 million, or 1.9%, from December 31, 2017. The growth in loans was primarily in commercial real estate, commercial business and residential real estate loans.

Asset Quality

The Bank's strategy for credit risk management focuses on having well-defined credit policies and uniform underwriting criteria and providing prompt attention to potential problem loans and leases. Performance of the loan and lease portfolio is monitored on a regular basis by Bank management and lending officers.

Loans and leases are deemed impaired when, based on current information and events, it is probable that the Bank will be unable to collect all proceeds due according to the original contractual terms of the agreement or when a loan or lease is classified as a troubled debt restructuring. Factors considered by management in determining impairment include payment status, borrower cash flows, collateral value and the probability of collecting scheduled principal and interest payments when due.

50

When a loan or lease, including a loan or lease that is impaired, is classified as nonaccrual, the accrual of interest on such a loan or lease is discontinued. A loan or lease is typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest, even though the loan or lease is currently performing. A loan or lease may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan or lease is placed on nonaccrual status, unpaid interest credited to income is reversed and the amortization of net deferred costs is suspended. Interest payments received on nonaccrual loans and leases are either applied against principal or reported as interest income, according to management’s judgment as to the ultimate collectability of principal.

Loans or leases are usually restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt.

At March 31, 2018, the recorded investment in loans and leases held for investment that were considered to be impaired was $41.8 million. The related reserve for loan and lease losses was $732 thousand. At December 31, 2017, the recorded investment in loans and leases that were considered to be impaired was $29.7 million. The related reserve for loan and lease losses was $131 thousand. During the first quarter of 2018, one commercial real-estate loan totaling $12.3 million was placed on non-accrual status. The impaired loan and lease balances consisted mainly of commercial real estate loans and business loans. Impaired loans and leases include nonaccrual loans and leases, accruing troubled debt restructured loans and lease modifications and other accruing impaired loans for which it is probable that not all principal and interest payments due will be collectible in accordance with the original contractual terms. The amount of the specific reserve needed for these credits could change in future periods subject to changes in facts and judgments related to these credits. Specific reserves have been established based on current facts and management’s judgments about the ultimate outcome of these credits.

Other real estate owned was $1.8 million at March 31, 2018 and December 31, 2017.

Reserve for Loan and Lease Losses

The reserve for loan and lease losses is maintained at a level representing management's best estimate of known risks and inherent losses in the portfolio, based upon management's evaluation of the portfolio's collectability. Management evaluates the need to establish reserves against losses on loans and leases on a quarterly basis. When changes in the reserve are necessary, an adjustment is made.

The reserve for loan and lease losses consists of a reserve for impaired loans and leases and a general valuation allowance on the remainder of the originated portfolio. Although management determines the amount of each element of the reserve separately, the entire reserve for loan and lease losses is available for losses on the portfolio. The Corporation records a provision for loan loss for the acquired non-impaired loans only when additional deterioration of the portfolio is identified over the projections utilized in the initial fair value analysis. After the acquisition measurement period, the present value of any decreases in expected cash flows of acquired credit impaired loans will generally result in an impairment charge recorded as a provision for loan loss, resulting in an increase to the allowance.

The Corporation maintains a reserve in other liabilities for off-balance sheet credit exposures that currently are unfunded in categories with historical loss experience. The reserve for these off-balance sheet credits was $411 thousand and $390 thousand at March 31, 2018 and December 31, 2017, respectively.

Goodwill and Other Intangible Assets

Goodwill and other intangible assets have been recorded on the books of the Corporation in connection with acquisitions. The Corporation has covenants not to compete, core deposit and customer-related intangibles and servicing rights, which are not deemed to have an indefinite life and therefore will continue to be amortized over their useful life using the present value of projected cash flows. The amortization of intangible assets was $899 thousand and $1.1 million for the three months ended March 31, 2018 and 2017, respectively. See Note 5 to the Consolidated Financial Statements, "Goodwill and Other Intangible Assets," for a summary of intangible assets at March 31, 2018 and December 31, 2017. The Corporation also has goodwill with a net carrying value of $172.6 million at March 31, 2018 and December 31, 2017, which is deemed to be an indefinite intangible asset and is not amortized.

The Corporation completes a goodwill impairment analysis at least on an annual basis, or more often, if events and circumstances indicate that there may be impairment. The Corporation also completes an impairment test for other identifiable intangible assets on an annual basis or more often if events and circumstances indicate there may be impairment. There was no impairment of goodwill or identifiable intangibles during the three months ended March 31, 2018 and 2017. Since the last annual impairment analysis during 2017, there have been no circumstances to indicate impairment. There can be no assurance that future impairment assessments or tests will not result in a charge to earnings.

Total liabilities	$	4,007,240	$	3,951,488	$	55,752		1.4	%

Deposits

Total deposits declined $57.6 million, or 1.6%, from December 31, 2017, primarily due to a decrease in commercial noninterest- bearing deposits and a seasonal decline in public funds deposits.

Borrowings

Total borrowings increased$110.9 million from December 31, 2017, primarily due to an increase in short-term borrowings of $111.0 million. The Corporation increased its short-term borrowings to fund loan growth and replace the decrease in deposits during the first quarter of 2018.

Shareholders’ Equity

The following table presents total shareholders’ equity at the dates indicated:

(Dollars in thousands)	At March 31, 2018			At December 31, 2017			Change
							Amount			Percent
Common stock	$	157,784		$	157,784		$	—		N/M
Additional paid-in capital	290,095			290,133			(38		)	N/M
Retained earnings	228,097			216,761			11,336			5.2
Accumulated other comprehensive loss	(26,791		)	(17,771		)	(9,020		)	(50.8	)

Total shareholders’ equity	$	606,719		$	603,374		$	3,345		0.6	%

The increase in shareholder's equity at March 31, 2018 of $3.3 million from December 31, 2017 was primarily related to an increase in retained earnings of $11.3 million. Retained earnings at March 31, 2018 were impacted by the three months of net income of $12.9 million and the reclassification of $3.9 million and $433 thousand from accumulated other comprehensive income related to the January 1, 2018 adoption of ASU 2016-01 and ASU 2018-02, respectively, partially offset by cash dividends declared of $5.9 million. Accumulated other comprehensive loss increased by $9.0 million mainly attributable to decreases in the fair value of available-for-sale investment securities of $5.0 million, net of tax, and the reclassification to retained earnings from the previously discussed adoption of ASU 2016-01 and ASU 2018-02 ($3.0 million related to the defined benefit pension plans and $1.4 million related to investment securities). Treasury stock decreased by $1.1 million primarily due to the issuance of restricted stock.

Capital Adequacy

The Corporation and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s and the Bank’s financial statements. Capital adequacy guidelines, and additionally for the Bank the prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Corporation and the Bank to maintain minimum amounts and ratios (set forth in the following table) of Total capital, Tier 1 capital and Tier 1 common capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined), or leverage ratio.

In July 2013, the federal bank regulatory agencies adopted final rules revising the agencies’ capital adequacy guidelines and prompt corrective action rules, designed to enhance such requirements and implement the revised standards of the Basel Committee on Banking Supervision, commonly referred to as Basel III. The new minimum capital requirements were effective on January 1, 2015. Under the new rules, in order to avoid limitations on capital distributions (including dividend payments and certain discretionary bonus payments to executive officers), a banking organization must hold a capital conservation buffer comprised of common equity Tier 1 capital above its minimum risk-based capital requirements in an amount greater than 2.5% of total risk-weighted assets. The capital conservation buffer requirements began to be phased in over a four-year period beginning January 1, 2016 with final phase in occurring 2019.

The Corporation adopted the new Basel III regulatory capital rules during the first quarter of 2015 under the transition rules, primarily relating to regulatory deductions and adjustments impacting common equity tier 1 capital and tier 1 capital, to be phased in over a four-year period beginning January 1, 2015. Under Basel III rules, the decision was made to opt-out of including accumulated other comprehensive income in regulatory capital. During 2018, the Corporation and the Bank must hold a capital conservation buffer greater than 1.875% above its minimum risk-based capital requirements in order to avoid limitations on capital distributions. It is the Corporation's and Bank's intent to maintain capital levels in excess of the capital conservation buffer which would require Tier 1 Capital to Risk Weighted Assets to exceed 8.50% and Total Capital to Risk Weighted Assets to exceed 10.50% beginning in the first quarter of 2019.

At March 31, 2018 and December 31, 2017, management believes that the Corporation and the Bank continued to meet all capital adequacy requirements to which they are subject. The Corporation, like other bank holding companies, currently is required to maintain Tier 1 capital and Total capital equal to at least 6.0% and 8.0%, respectively, of total risk-weighted assets (including various off-balance-sheet items). The Bank, like other depository institutions, is required to maintain similar capital levels under capital adequacy guidelines. During 2018, the Corporation and the Bank must hold a capital conservation buffer comprised of common equity Tier 1 capital above its minimum risk-based capital requirements in an amount greater than 1.875% of total risk-weighted assets in order to avoid limitations on capital distributions. For a depository institution to be considered “well capitalized” under the regulatory framework for prompt corrective action, Tier 1 and Total capital ratios must be at least 8.0% and 10.0% on a risk-adjusted basis, respectively. At March 31, 2018, the Bank is categorized as “well capitalized” under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Corporation will continue to analyze the impact of the phase in of the capital conservation buffer as well as the impact of new accounting rules, such as Lease Accounting (ASU No. 2016-02) and CECL (ASU No. 2016-13) on its regulatory capital ratios. See Note 1 to the financial statements included in Part I, Item I of this Form 10-Q for additional information.

Asset/Liability Management

The primary functions of Asset/Liability Management are to assure adequate earnings, capital and liquidity while maintaining an appropriate balance between interest-earning assets and interest-bearing liabilities. Liquidity management involves the ability to meet cash flow requirements of customers and corporate needs. Management's objective to address interest rate risk is to understand the Corporation's sensitivity to changes in interest rates and develop and implement strategies to minimize volatility while maximizing net interest income.

The Corporation uses both interest-sensitivity gap analysis and simulation modeling to quantify exposure to interest rate risk. The Corporation uses the gap analysis to identify and monitor long-term rate exposure and uses a simulation model to measure the short-term rate exposures. The Corporation runs various earnings simulation scenarios to quantify the impact of declining or rising interest rates on net interest income over a one-year and two-year horizon. The simulation uses expected cash flows and repricing characteristics for all financial instruments at a point in time and incorporates company developed, market-based assumptions regarding growth, pricing, and optionality such as prepayment speeds. As interest rates increase, fixed-rate assets that banks hold will tend to decrease in value; conversely, as interest rates decline, fixed-rate assets that banks hold will tend to increase in value.

Liquidity

The Corporation, in its role as a financial intermediary, is exposed to certain liquidity risks. Liquidity refers to the Corporation’s ability to ensure that sufficient cash flow and liquid assets are available to satisfy demand for loans, deposit withdrawals, repayment of borrowings and certificates of deposit at maturity, operating expenditures, and capital expansion. The Corporation manages liquidity risk by measuring and monitoring liquidity sources and estimated funding needs on a daily basis. The Corporation has a contingency funding plan in place to address liquidity needs in the event of an institution-specific or a systemic financial crisis.

Sources of Funds

Core deposits continue to be the largest significant funding source for the Corporation. These deposits are primarily generated from a base of consumer, business, municipalities and non-profit customers located in our primary service areas. The Corporation faces increased competition for these deposits from a large array of financial market participants, including banks, credit unions, savings institutions, mutual funds, security dealers and others.

The Corporation also utilizes a mix of short-term and long-term wholesale funding providers. Wholesale funding includes correspondent bank borrowings, secured borrowing lines from the Federal Home Loan Bank, the Federal Reserve Bank of Philadelphia and, at times, brokered deposits and other similar sources.

The Corporation, through the Bank, has a credit facility with the FHLB with a maximum borrowing capacity of approximately $1.5 billion. At March 31, 2018 and December 31, 2017, the carrying amount of overnight borrowings with the FHLB was $148.3 million and $30.2 million, respectively. At March 31, 2018 and December 31, 2017, the carrying amount of long-term borrowings with the FHLB was $125.0 million. At March 31, 2018 and December 31, 2017, the Bank had outstanding short-term letters of credit with the FHLB totaling $198.0 million and $234.2 million, respectively, which were utilized to collateralize public funds deposits. The maximum borrowing capacity with the FHLB changes as a function of qualifying collateral assets as well as the FHLB’s internal credit rating of the Bank.

The Corporation, through the Bank, maintains uncommitted federal fund lines with several correspondent banks totaling $367.0 million at March 31, 2018 and December 31, 2017. At March 31, 2018 and December 31, 2017, the Corporation had $50.0 million and $55.0 million, respectively, outstanding federal funds purchased with these correspondent banks. Future availability under these lines is subject to the prerogatives of the granting banks and may be withdrawn at will.

The Corporation, through the Bank, holds collateral at the Federal Reserve Bank of Philadelphia in order to access their Discount Window Lending program. The collateral consisting of investment securities was valued at $68.5 million and $52.0 million at March 31, 2018 and December 31, 2017, respectively. At March 31, 2018 and December 31, 2017, the Corporation had no outstanding borrowings under this program.

The Corporation has a $10.0 million line of credit with a correspondent bank. At March 31, 2018, the Corporation had no outstanding borrowings under this line.

56

Cash Requirements

The Corporation has cash requirements for various financial obligations, including contractual obligations and commitments that require cash payments. The most significant contractual obligation, in both the under and over one year time period, is for the Bank to repay certificates of deposit and short-term and long-term borrowings. The Bank anticipates meeting these obligations by continuing to provide convenient depository and cash management services through its financial center network, thereby replacing these contractual obligations with similar fund sources at rates that are competitive in our market. The Bank will also use borrowings and brokered deposits to meet its obligations.

Commitments to extend credit are the Bank’s most significant commitment in both the under and over one year time periods. These commitments do not necessarily represent future cash requirements in that these commitments often expire without being drawn upon.

Recent Accounting Pronouncements

For information regarding recent accounting pronouncements, refer to Note 1 to the Consolidated Financial Statements, “Summary of Significant Accounting Policies.”

Item 3. Quantitative and Qualitative Disclosures About Market Risk

No material changes in the Corporation’s market risk or market strategy occurred during the current period. A detailed discussion of market risk is provided in the Corporation's Annual Report on Form 10-K for the year ended December 31, 2017.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Management is responsible for the disclosure controls and procedures of the Corporation. Disclosure controls and procedures are controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods required by the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be so disclosed by an issuer is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. As of the end of the period covered by this report, an evaluation was performed under the supervision and with the participation of the Corporation’s management, including the Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial and Accounting Officer), of the effectiveness of the design and operation of the Corporation’s disclosure controls and procedures. Based on that evaluation, the Corporation’s Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective as of March 31, 2018.

Changes in Internal Control over Financial Reporting

There were no changes in the Corporation’s internal control over financial reporting (as defined in Rule 13a-15(f)) during the quarter ended March 31, 2018 that materially affected, or are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

57

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of Univest Corporation of Pennsylvania (the Corporation or Univest) and its wholly owned subsidiaries. The Corporation’s direct subsidiary is Univest Bank and Trust Co. (the Bank). All significant intercompany balances and transactions have been eliminated in consolidation. The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations for interim financial information. The accompanying unaudited consolidated financial statements reflect all adjustments which are of a normal recurring nature and are, in the opinion of management, necessary for a fair presentation of the financial statements for the interim periods presented. Certain prior period amounts have been reclassified to conform to the current-year presentation. Operating results for the three-month period ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ended December 31, 2018 or for any other period. It is suggested that these unaudited consolidated financial statements be read in conjunction with the audited financial statements and the notes thereto included in the registrant’s Annual Report on Form 10-K for the year ended December 31, 2017, which was filed with the SEC on March 1, 2018.

Use of Estimates

The preparation of the unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include fair value measurement of investment securities available-for-sale, reserve for loan and lease losses and purchase accounting.

Accounting Pronouncements Adopted in 2018

In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-02, "Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This ASUclarifies the accounting treatment of the reclassification of certain income tax effects within accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act. The Corporation elected to early adopt this guidance effective January 1, 2018 for all stranded tax effects resulting from tax reform and reclassified stranded tax effects, totaling $3.9 million, from accumulated other comprehensive income to retained earnings. The Corporation's policy for releasing income tax effects from accumulated other comprehensive income is to release such effects on an individual basis as each item is liquidated, sold or extinguished. See Note 10, "Accumulated Other Comprehensive (Loss) Income" for additional detail.

In March 2017, the FASB issued ASU No. 2017-07, "Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The amendments in this ASU require that an employer that sponsors defined benefit pension plans and other postretirement plans present the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. Other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The Corporation adopted this guidance effective January 1, 2018 with retrospective application for prior period presentation. Effective January 1, 2018, components of net benefit income other than the service cost component are presented in the Corporation's statement of income in other noninterest expense rather than in salaries, benefits and commission expense. Prior period components of net benefit income other than the service cost component were reclassed to other noninterest expense in the Corporation's statement of income.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." This ASU addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The ASU requires equity investments to be measured at fair value with changes in fair value recognized in net income. At December 31, 2017, the Corporation's equity portfolio had a carrying value of $1.1 million which included an unrealized net gain of $666 thousand. At December 31, 2017, $433 thousand was recorded in accumulated other comprehensive income which represented the unrealized net gain, net of income taxes, based on the Corporation’s statutory tax rate as of December 31, 2017. The Corporation adopted this guidance effective January 1, 2018 with a cumulative-effect adjustment to the balance sheet as of January 1, 2018. The balance in accumulated other comprehensive income of $433 thousand was reclassified to retained earnings effective January 1, 2018. The carrying value of the equity securities, at January 1, 2018, did not change; however, any future increases or decreases in fair value is recorded as an increase or decrease to the carrying value and recognized in other noninterest income. During the three months ended March 31, 2018, the Corporation recognized a $4 thousand net loss on equity securities in other noninterest income.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)” and subsequent related updates. The Corporation adopted the guidance effective January 1, 2018 using the modified retrospective method though no adjustments were made to retained earnings as a result of the adoption. The Corporation provided expanded disclosures related to recognition of revenue from contracts with customers. See Note 14, "Revenue from Contracts with Customers."

Recent Accounting Pronouncements Yet to Be Adopted

In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." The amendments in this update expand and refine hedge accounting for both non-financial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. Additional hedging strategies permitted for hedge accounting include: hedges of contractually-specified price components of commodity purchases or sales, hedges of the benchmark rate component of the contractual coupon cash flows of fixed-rate assets or liabilities, hedges of the portion of a closed portfolio of prepayable assets not expected to prepay, and partial-term hedges of fixed-rate assets or liabilities. The ASU amends the presentation and disclosure requirements and changes how entities assess effectiveness. The ASU eliminates the requirement to separately measure and report hedge ineffectiveness and requires all items that affect earnings be presented in the same income statement line as the hedged items. After initial qualification, the new guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test, such as a regression analysis, if the entity can reasonably support an expectation of high effectiveness throughout the term of the hedge. An initial quantitative test to establish that the hedge relationship is highly effective is still required. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for public business entities, or January 1, 2019 for the Corporation. Early adoption is permitted, including an interim period. The amended presentation and disclosure guidance is required only prospectively. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements.

In March 2017, the FASB issued ASU No. 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” This ASU shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, or January 1, 2019 for the Corporation. Early adoption is permitted, including an interim period. This ASU is to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This ASU eliminates Step 2 of the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the new guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, or for the Corporation's goodwill impairment test in 2020. Early adoption is permitted for goodwill impairment tests with measurement dates after January 1, 2017. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU requires businesses and other organizations to measure the current expected credit losses (CECL) on financial assets, such as loans, net investments in leases, certain debt securities, bond insurance and other receivables. The amendments affect entities holding financial assets and net investments in leases that are not accounted for at fair value through net income. Current GAAP requires an incurred loss methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. The amendments in this ASU replace the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonableness and supportable information to inform credit loss estimates. An entity should apply the amendments through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (modified-retrospective approach). Acquired credit impaired loans for which the guidance in Accounting Standards Codification (ASC) Topic 310-30 has been previously applied should prospectively apply the guidance in this ASU. A prospective transition approach is required for debt securities for which an other-than-temporary impairment has been recognized before the effective date. The ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those years for public business entities that are SEC filers, or January 1, 2020 for the Corporation. The Corporation is in the process of evaluating the impact of the adoption of this guidance on the Corporation's financial statements; however, it is anticipated that the allowance will increase upon adoption of CECL and that the increased allowance level will decrease shareholders' equity and regulatory capital and ratios.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" to revise the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases. Disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. The ASU is effective for the first interim period within annual periods beginning after December 15, 2018, or January 1, 2019, with early adoption permitted. The Corporation is in the process of evaluating the impact of the adoption of this guidance on the Corporation's financial statements; however, the adoption of this ASU will impact the balance sheet for the recording of assets and liabilities for operating leases; any initial or continued impact of the recording of assets will have a negative impact on all Corporation and Bank capital ratios under current regulatory guidance and possibly equity ratios.

Earnings Per Share, Basic and Diluted [Abstract]

Earnings per Share

Earnings per Share

The Corporation uses the two-class method to calculate earnings per share as the unvested restricted stock issued under the Corporation's equity incentive plans are participating shares with nonforfeitable rights to dividends. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the number of weighted average shares outstanding during the period. The table also notes anti-dilutive options which are those options with weighted average exercise prices in excess of the weighted average market value for the periods presented.

The following table sets forth the computation of basic and diluted earnings per share:

N/A - Not applicable as a result of adoption of ASU 2016-01

Expected maturities may differ from contractual maturities because debt issuers may have the right to call or prepay obligations without call or prepayment penalties and mortgage-backed securities typically prepay at a rate faster than contractually due.

Securities with a carrying value of $362.5 million and $345.1 million at March 31, 2018 and December 31, 2017, respectively, were pledged to secure public deposits and other contractual obligations. In addition, securities of $296 thousand and $1.8 million were pledged to secure credit derivatives and interest rate swaps at March 31, 2018 and December 31, 2017, respectively. See Note 11, "Derivative Instruments and Hedging Activities" for additional information.

The following table presents information related to sales of securities available-for-sale during the three months ended March 31, 2018 and 2017:

	Three Months Ended March 31,

Securities available-for-sale:
Proceeds from sales	$	1,010	$	1,762
Gross realized gains on sales	10		15

At March 31, 2018 and December 31, 2017, there were no investments in any single non-federal issuer representing more than 10% of shareholders’ equity.

The following table shows the fair value of securities that were in an unrealized loss position at March 31, 2018 and December 31, 2017 by the length of time those securities were in a continuous loss position. For the investment securities in an unrealized loss position, the Corporation has concluded, based on its analysis, that the unrealized losses are primarily caused by the movement of interest rates and current market conditions. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the par value of the investment. It is more likely than not that the Corporation will not be required to sell the investments before a recovery of carrying value.

At March 31, 2018, gross unrealized losses for securities in an unrealized loss position for twelve months or longer, totaled $12.0 million. Four federal agency bonds, thirteen investment grade corporate bonds, 105 federal agency residential mortgage securities, and seven investment grade municipal bonds had respective unrealized loss positions of $105 thousand, $6.7 million, $5.2 million and $51 thousand, respectively. The fair value of these 129 securities fluctuate with changes in market conditions which for these underlying securities is primarily due to changes in the interest rate environment. The Corporation does not intend to sell the securities in an unrealized loss position and is unlikely to be required to sell these securities before a recovery of fair value, which may be maturity. Upon review of the attributes of the individual securities, the Corporation concluded these securities were not other-than-temporarily impaired. The Corporation did not recognize any other-than-temporary impairment charges on debt securities for the three months ended March 31, 2018 and 2017.

In conjunction with the adoption of ASU 2016-01, the Corporation recognized a $4 thousand net loss on equity securities during the three months ended March 31, 2018 in other noninterest income and the net unrealized loss on equity securities held at March 31, 2018 was $4 thousand. See Note 1, "Summary of Significant Accounting Policies - Accounting Pronouncements Adopted in 2018" for additional information.

* Includes nonaccrual troubled debt restructured loans and lease modifications of $1.7 million and $2.5 million at March 31, 2018 and December 31, 2017, respectively.

Accruing troubled debt restructuring loans of $11.4 million at December 31, 2017 includes balances of $10.3 million related to one borrower which were classified as troubled debt restructurings as the related loans were granted amortization period extensions. These troubled debt restructured loans were returned to performing status during the first quarter of 2018 as the borrower was in compliance with the modified terms of the restructurings for the required time period. At March 31, 2018, commercial real estate nonaccrual loans and leases includes a $12.3 million loan that was placed on nonaccrual status during the current quarter. A specific reserve of $656 thousand was recorded for this loan as of March 31, 2018.

Credit Quality Indicators

The following tables present by class, the recorded investment in loans and leases held for investment by credit quality indicator at March 31, 2018 and December 31, 2017.

The Corporation employs a ten (10) grade risk rating system related to the credit quality of commercial loans and residential real estate loans secured for a business purpose of which the first six categories are pass categories (credits not adversely rated).The following is a description of the internal risk ratings and the likelihood of loss related to each risk rating. Loans with a relationship balance of less than $1 million are reviewed on a performance basis, with the primary monitored metrics being delinquency (60 days or more past due) and revolving stagnancy. Loans with relationships greater than $1 million are reviewed at least annually.  Loan relationships exceeding $15 million or classified as special mention or substandard are reviewed at least quarterly, or more frequently based on management’s discretion. 

1. Cash Secured—No credit risk

2. Fully Secured—Negligible credit risk

3. Strong—Minimal credit risk

4. Satisfactory—Nominal credit risk

5. Acceptable—Moderate credit risk

6. Pre-Watch—Marginal, but stable credit risk

7. Special Mention—Potential weakness

8. Substandard—Well-defined weakness

9. Doubtful—Collection in-full improbable

10. Loss—Considered uncollectible

Credit Exposure—Real Estate—Residential Secured for Personal Purpose, Real Estate—Home Equity Secured for Personal Purpose, Loans to individuals, Lease Financing Credit Risk Profile by Payment Activity

The Corporation monitors the credit risk profile by payment activity for the following classifications of loans and leases: residential real estate loans secured for a personal purpose, home equity loans secured for a personal purpose, loans to individuals and lease financings. Nonperforming loans and leases are loans and leases past due 90 days or more, loans and leases on nonaccrual of interest and troubled debt restructured loans and lease modifications. Performing loans and leases are reviewed only if the loan becomes 60 days or more past due. Nonperforming loans and leases are reviewed monthly. Performing loans and leases have a nominal to moderate risk of loss.

The Corporation records a provision for loan loss for the acquired non-impaired loans only when additional deterioration of the portfolio is identified over the projections utilized in the initial fair value analysis. After the acquisition measurement period, the present value of any decreases in expected cash flows of acquired credit impaired loans will generally result in an impairment charge recorded as a provision for loan loss, resulting in an increase to the allowance.

Impaired loans include nonaccrual loans, accruing troubled debt restructured loans and other accruing impaired loans for which it is probable that not all principal and interest payments due will be collectible in accordance with the original contractual terms. These loans are individually measured to determine the amount of potential impairment. The loans are reviewed for impairment based on the fair value of the collateral for collateral dependent loans and for certain loans based on discounted cash flows using the loans’ initial effective interest rates. Impaired loans include other accruing impaired loans of $3.3 million and $4.1 million at March 31, 2018 and December 31, 2017, respectively. Specific reserves on other accruing impaired loans were $28 thousand and $99 thousand at March 31, 2018 and December 31, 2017, respectively.

The following presents by class of loans, the average recorded investment in impaired loans and an analysis of interest on impaired loans. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. Therefore, interest income on accruing impaired loans is recognized using the accrual method.

Impaired Leases

The Corporation had impaired leases of $1.3 million at March 31, 2018 and December 31, 2017 with no related reserves. See discussion in Reserve for Loan and Lease Losses and Recorded Investment in Loans and Leases.

Troubled Debt Restructured Loans

There were no loans restructured during the three months ended March 31, 2018 and March 31, 2017.

The Corporation grants concessions to existing borrowers primarily related to extensions of interest-only payment periods and an occasional payment modification. These modifications typically are for up to one year. The goal when restructuring a credit is to establish a reasonable period of time to provide cash flow relief to customers experiencing cash flow difficulties. Accruing troubled debt restructured loans are primarily comprised of loans on which interest is being accrued under the restructured terms, and the loans are current or less than ninety days past due.

The following presents, by class of loans, information regarding accruing and nonaccrual troubled debt restructured loans, for which there were payment defaults within twelve months of the restructuring date:

The Corporation has originated mortgage servicing rights, which are included in other intangible assets on the consolidated balance sheets. Mortgage servicing rights are amortized in proportion to, and over the period of, estimated net servicing income on a basis similar to the interest method and an accelerated amortization method for loan payoffs. Mortgage servicing rights are subject to impairment testing on a quarterly basis. The aggregate fair value of these rights was $11.2 million at March 31, 2018 and $10.0 million at December 31, 2017. The fair value of mortgage servicing rights was determined using a discount rate of 10.0% at March 31, 2018 and December 31, 2017. The Corporation also records servicing rights on small business administration (SBA) loans. The value of these servicing rights was $20 thousand and $21 thousand at March 31, 2018 and December 31, 2017, respectively.

The Corporation, through the Bank, has a credit facility with the Federal Home Loan Bank (FHLB) with a maximum borrowing capacity of approximately $1.5 billion. Advances from the FHLB are collateralized by a blanket floating lien on all first mortgage loans of the Bank, FHLB capital stock owned by the Bank and any funds on deposit with the FHLB. At March 31, 2018 and December 31, 2017, the Bank had outstanding short-term letters of credit with the FHLB totaling $198.0 million and $234.2 million, respectively, which were utilized to collateralize public funds deposits. The maximum borrowing capacity with the FHLB changes as a function of the Bank’s qualifying collateral assets as well as the FHLB’s internal credit rating of the Bank.    

The Corporation, through the Bank, maintains uncommitted federal fund credit lines with several correspondent banks totaling $367.0 million at March 31, 2018 and December 31, 2017.

Retirement Plans and Other Postretirement Benefits

Retirement Plans and Other Postretirement Benefits

Substantially all employees who were hired before December 8, 2009 are covered by a noncontributory retirement plan. Employees hired on or after December 8, 2009 are not eligible to participate in the noncontributory retirement plan. The Corporation also provides supplemental executive retirement benefits to certain former executives, a portion of which is in excess of limits imposed on qualified plans by federal tax law; these plans are non-qualified benefit plans. These non-qualified benefit plans are not offered to new participants; all current participants are now retired. Information on these plans are aggregated and reported under “Retirement Plans” within this footnote.

The Corporation also provides certain postretirement healthcare and life insurance benefits for retired employees. Information on these benefits is reported under “Other Postretirement Benefits” within this footnote.

The Corporation sponsors a Supplemental Non-Qualified Pension Plan, which was established in 1981 prior to the existence of a 401(k) deferred salary savings plan, employee stock purchase plan and long-term incentive plans and therefore is not offered to new participants; all current participants are now retired.

Components of net periodic benefit cost (income) were as follows:

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities

Interest Rate Swaps

The Corporation may use interest rate swap agreements to modify interest rate characteristics from variable to fixed or fixed to variable in order to reduce the impact of interest rate changes on future net interest income. Recorded amounts related to interest-rate swaps are included in other assets or liabilities. The Corporation’s credit exposure on interest rate swaps includes fair value and any collateral that is held by a third party. Changes in the fair value of derivative instruments designated as hedges of future cash flows are recognized in accumulated other comprehensive income until the underlying forecasted transactions occur, at which time the deferred gains and losses are recognized in earnings. For a qualifying fair value hedge, the gain or loss on the hedging instrument is recognized in earnings, and the change in fair value of the hedge item, to the extent attributable to the hedged risk, adjusts the carrying amount of the hedge item and is recognized in earnings.

In 2014, the Corporation entered into an amortizing interest rate swap classified as a cash flow hedge with a notional amount of $20.0 million to hedge a portion of the debt financing of a pool of 10-year maturity fixed rate loans with balances totaling $29.1 million, at time of the hedge, that were originated in 2013. A brokered money market demand account with a balance exceeding the amortizing interest rate swap balance is being used for the cash flow hedge. Under the terms of the swap agreement, the Corporation pays a fixed rate of 2.10% and receives a floating rate of one-monthLIBOR. The swap matures in November 2022. The Corporation performed an assessment of the hedge for effectiveness at the inception of the hedge and on a recurring basis to determine that the derivative has been and is expected to continue to be highly effective in offsetting changes in cash flows of the hedged item. The Corporation expects that there will be no ineffectiveness over the life of the interest rate swap. At March 31, 2018, there is no gain or loss recorded in accumulated other comprehensive loss that is expected to be reclassified into earnings during the next twelve months. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to March 31, 2018. At March 31, 2018, the notional amount of the interest rate swap was $17.6 million, with a positive fair value of $294 thousand.

The Corporation has an interest rate swap classified as a fair value hedge with a current notional amount of $1.4 million to hedge a 10-year fixed rate loan that is earning interest at 5.83%. The Corporation pays a fixed rate of 5.83% and receives a floating rate based on the one-month LIBOR plus 350 basis points. The swap matures in October 2021. The difference between changes in the fair values of the interest rate swap agreement and the hedged loan represents hedge ineffectiveness and is recorded in other noninterest income in the consolidated statements of operations.

The Corporation has an interest rate swap with a current notional amount of $497 thousand, for a 15-year fixed rate loan that is earning interest at 7.43%. The Corporation pays a fixed rate of 7.43% and receives a floating rate based on the one-month LIBOR plus 224 basis points. The swap matures in April 2022. The interest rate swap is carried at fair value in accordance with FASB ASC 815 "Derivatives and Hedging." The loan is carried at fair value under the fair value option as permitted by FASB ASC 825 "Financial Instruments."

Credit Derivatives

The Corporation has agreements with third-party financial institutions whereby the third-party financial institution enters into interest rate derivative contracts and foreign currency swap contracts with loan customers referred to them by the Corporation. By the terms of the agreements, the third-party financial institution has recourse to the Corporation for any exposure created under each swap contract in the event the customer defaults on the swap agreement and the agreement is in a paying position to the third-party financial institution. These transactions represent credit derivatives and are a customary arrangement that allows the Corporation to provide access to interest rate and foreign currency swap transactions for customers without creating the swap. The Corporation records the fair value of credit derivatives in other liabilities on the consolidated balance sheets. The Corporation recognizes changes in the fair value of credit derivatives, net of any fees received, in other noninterest income in the consolidated statements of income.

At March 31, 2018, the Corporation has fifteen variable-rate to fixed-rate interest rate swap transactions between the third-party financial institution and customers with a current notional amount of $75.0 million, and remaining maturities ranging from one to 10 years. At March 31, 2018, the fair value of the swaps to the customers was a liability of $31 thousand and all swaps were in paying positions to the third-party financial institution.

At March 31, 2018, there were no material foreign currency swap transactions between the third-party institution and loan customers.

The maximum potential payments by the Corporation to the third-party financial institution under these credit derivatives are not estimable as they are contingent on future interest rates and exchange rates, and the agreement does not provide for a limitation of the maximum potential payment amount.

Mortgage Banking Derivatives

Derivative loan commitments represent agreements for delayed delivery of financial instruments in which the buyer agrees to purchase and the seller agrees to deliver, at a specified future date, a specified instrument at a specified price or yield. The Corporation’s derivative loan commitments are commitments to sell loans secured by 1-to 4-family residential properties whose predominant risk characteristic is interest rate risk. The fair values of these derivative loan commitments are based upon the estimated amount the Corporation would receive or pay to terminate the contracts or agreements, taking into account current interest rates and, when appropriate, the current creditworthiness of the counterparties.

Fair Value Disclosures [Abstract]

Fair Value Disclosures

Fair Value Disclosures

Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The Corporation determines the fair value of financial instruments based on the fair value hierarchy. The Corporation maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Corporation. Unobservable inputs are inputs that reflect the Corporation’s assumptions that market participants would use in pricing the asset or liability based on the best information available in the circumstances, including assumptions about risk. Three levels of inputs are used to measure fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement. Transfers between levels are recognized at the end of the reporting period.

Level 1: Valuations are based on quoted prices in active markets for identical assets or liabilities that the Corporation can access at the measurement date. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment.

Level 2: Valuations are based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3: Valuations are based on inputs that are unobservable and significant to the overall fair value measurement. Assets and liabilities utilizing Level 3 inputs include: financial instruments whose value is determined using pricing models, discounted cash-flow methodologies, or similar techniques, as well as instruments for which the fair value calculation requires significant management judgment or estimation.

Following is a description of the valuation methodologies used for instruments measured at fair value on a recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy.

Investment Securities

Where quoted prices are available in an active market for identical instruments, investment securities are classified within Level 1 of the valuation hierarchy. Level 1 investment securities include U.S. Treasury securities, most equity securities and money market mutual funds. Mutual funds are registered investment companies which are valued at net asset value of shares on a market exchange at the end of each trading day. Level 2 of the valuation hierarchy includes securities issued by U.S. Government sponsored enterprises, mortgage-backed securities, collateralized mortgage obligations, corporate and municipal bonds and certain equity securities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. In cases where there is limited activity or less transparency around inputs to the valuation, investment securities are classified within Level 3 of the valuation hierarchy.

Fair values for securities are determined using independent pricing services and market-participating brokers. The Corporation’s independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information for structured securities, cash flow and, when available, loan performance data. Because many fixed income securities do not trade on a daily basis, the pricing service’s evaluated pricing applications apply information as applicable through processes, such as benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations. If at any time, the pricing service determines that it does not have sufficient verifiable information to value a particular security, the Corporation will utilize valuations from another pricing service. Management has a sufficient understanding of the third party service’s valuation models, assumptions and inputs used in determining the fair value of securities to enable management to maintain an appropriate system of internal control.

Certain corporate bonds owned by the Corporation are classified as Level 3 as they are not traded in active markets. The fair value of each bond is estimated by benchmarking similar transactions of structure, yield and credit which are owned by the Corporation and are actively traded in the market.

On a quarterly basis, the Corporation reviews changes, as submitted by the pricing service, in the market value of its security portfolio. Individual changes in valuations are reviewed for consistency with general interest rate movements and any known credit concerns for specific securities. If, upon the Corporation’s review or in comparing with another service, a material difference between pricing evaluations were to exist, the Corporation may submit an inquiry to the current pricing service regarding the data used to determine the valuation of a particular security. If the Corporation determines there is market information that would support a different valuation than from the current pricing service’s evaluation, the Corporation may utilize and change the security's valuation. There were no material differences in valuations noted at March 31, 2018.

Derivative Financial Instruments

The fair values of derivative financial instruments are based upon the estimated amount the Corporation would receive or pay to terminate the contracts or agreements, taking into account current interest rates and, when appropriate, the current creditworthiness of the counterparties. Interest rate swaps and mortgage banking derivative financial instruments are classified within Level 2 of the valuation hierarchy. Credit derivatives are valued based on credit worthiness of the underlying borrower which is a significant unobservable input and therefore classified in Level 3 of the valuation hierarchy.

Two commercial loans associated with interest rate swaps are classified in Level 3 of the valuation hierarchy since lending credit risk is not an observable input for these loans. The unrealized gain on the two loans was $27 thousand at March 31, 2018.

Contingent Consideration Liability

The Corporation estimates the fair value of the contingent consideration liability by using a discounted cash flow model of future contingent payments based on projected revenue related to the acquired business. The estimated fair value of the contingent consideration liability is reviewed on a quarterly basis and any valuation adjustments resulting from a change of estimated future contingent payments based on projected revenue of the acquired business affecting the contingent consideration liability will be recorded through noninterest expense. Due to the significant unobservable input related to the projected revenue, the contingent consideration liability is classified within Level 3 of the valuation hierarchy. An increase in the projected revenue may result in a higher fair value of the contingent consideration liability. Alternatively, a decrease in the projected revenue may result in a lower estimated fair value of the contingent consideration liability.

The following table presents the assets and liabilities measured at fair value on a recurring basis at March 31, 2018 and December 31, 2017, classified using the fair value hierarchy:

The following valuation methods and assumptions were used by the Corporation in estimating the fair value for financial instruments measured at fair value on a non-recurring basis and financial instruments not measured at fair value on a recurring or non-recurring basis in the Corporation’s consolidated balance sheets but for which the fair value is required to be disclosed:

Cash and short-term interest-earning assets: The carrying amounts reported in the balance sheet for cash and due from banks, interest-earning deposits with other banks, federal funds sold and other short-term investments is their stated value. Cash and short-term interest-earning assets are classified within Level 1 in the fair value hierarchy.

Held-to-maturity securities: Fair values for the held-to-maturity investment securities are estimated by using pricing models or quoted prices of securities with similar characteristics and are classified in Level 2 in the fair value hierarchy.

Federal Home Loan Bank, Federal Reserve Bank and other stock: It is not practical to determine the fair values of Federal Home Loan Bank, Federal Reserve Bank and other stock, due to restrictions placed on their transferability.

Loans held for sale: The fair value of the Corporation’s mortgage loans held for sale are generally determined using a pricing model based on current market information obtained from external sources, including interest rates, bids or indications provided by market participants on specific loans that are actively marketed for sale. These loans are primarily residential mortgage loans and are generally classified in Level 2 due to the observable pricing data. Loans held for sale are carried at the lower of cost or estimated fair value. There were no valuation adjustments for loans held for sale at March 31, 2018 and December 31, 2017.

Loans and leases held for investment: As of March 31, 2018, the fair values for loans and leases held for investment are estimated using discounted cash flow analyses, using a discount rate based on current interest rates at which similar loans with similar terms would be made to borrowers, adjusted as appropriate to consider credit, liquidity and marketability factors to arrive at a fair value that represents the Corporation's exit price at which these instruments would be sold or transferred. As of December 31, 2017, the fair values for loans and leases held for investment were estimated using discounted cash flow analyses, using a discount rate based on current interest rates at which similar loans with similar terms would be made to borrowers and include components for credit risk, operating expense and embedded prepayment options. An overall valuation adjustment was made for specific credit risks in addition to general portfolio risk and is significant to the valuation.Loans and leases are classified within Level 3 in the fair value hierarchy.

Impaired loans and leases held for investment: For impaired loans and leases, the Corporation uses a variety of techniques to measure fair value, such as using the current appraised value of the collateral, agreements of sale, discounting the contractual cash flows, and analyzing market data that the Corporation may adjust due to specific characteristics of the loan/lease or collateral. At March 31, 2018, impaired loans held for investment had a carrying amount of $40.6 million with a valuation allowance of $732 thousand. At December 31, 2017, impaired loans held for investment had a carrying amount of $28.5 million with a valuation allowance of $131 thousand. The Corporation had impaired leases of $1.3 million with no reserve at March 31, 2018 and December 31, 2017.

Servicing rights: The Corporation estimates the fair value of mortgage servicing rights using discounted cash flow models that calculate the present value of estimated future net servicing income. The model uses readily available prepayment speed assumptions for the interest rates of the portfolios serviced. Mortgage servicing rights are classified within Level 3 in the fair value hierarchy based upon management's assessment of the inputs. The Corporation reviews the mortgage servicing rights portfolio on a quarterly basis for impairment and the mortgage servicing rights are carried at the lower of amortized cost or estimated fair value. The Corporation also records servicing rights on SBA loans. At March 31, 2018 and December 31, 2017, servicing rights had a carrying amount of $6.6 million with no valuation allowance.

Goodwill and other identifiable assets: Certain non-financial assets subject to measurement at fair value on a non-recurring basis include goodwill and other identifiable intangible assets. During the three months ended March 31, 2018, there were no triggering events that required valuation of goodwill and other identifiable intangible assets.

Other real estate owned: The fair value of other real estate owned (OREO) is originally estimated based upon the appraised value less estimated costs to sell. The fair value less cost to sell becomes the "original cost" of the OREO asset. Subsequently, OREO is reported as the lower of the original cost and the current the fair value less cost to sell. Capital improvement expenses associated with the construction or repair of the property are capitalized as part of the cost of the OREO asset; however, the capitalized expenses may not increase the OREO asset's recorded value to an amount greater than the asset's fair value after improvements and less cost to sell. At March 31, 2018 and December 31, 2017, OREO had a carrying amount of $1.8 million. New appraisals are generally obtained on an annual basis if an agreement of sale does not exist. Other real estate owned is classified within Level 3 of the valuation hierarchy due to the unique characteristics of the collateral for each loan.

Deposit liabilities: The fair values for demand and savings accounts, with no stated maturities, is the amount payable on demand at the reporting date (carrying value) and are classified within Level 1 in the fair value hierarchy. The fair values for time deposits with fixed maturities are estimated by discounting the final maturity using interest rates currently offered for deposits with similar remaining maturities. Time deposits are classified within Level 2 in the fair value hierarchy.

Short-term borrowings: The fair value of short-term borrowings are estimated using current market rates for similar borrowings and are classified within Level 2 in the fair value hierarchy.

Long-term debt: The fair value of long-term debt is estimated by using discounted cash flow analysis, based on current market rates for debt with similar terms and remaining maturities. Long-term debt is classified within Level 2 in the fair value hierarchy.

Subordinated notes: The fair value of the subordinated notes are estimated by discounting the principal balance using the treasury yield curve for the term to the call date as the Corporation has the option to call the subordinated notes. The subordinated notes are classified within Level 2 in the fair value hierarchy.

Off-balance-sheet instruments: Fair values for the Corporation’s off-balance-sheet instruments are based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing and are classified within Level 2 in the fair value hierarchy.

Segment Reporting

Segment Reporting

At March 31, 2018, the Corporation has three reportable business segments: Banking, Wealth Management and Insurance. The Corporation determines the segments based primarily upon product and service offerings, through the types of income generated and the regulatory environment. This is strategically how the Corporation operates and has positioned itself in the marketplace. Accordingly, significant operating decisions are based upon analysis of each of these segments. The parent holding company and intercompany eliminations are included in the "Other" segment.

The Corporation's Banking segment consists of commercial, consumer and mortgage banking as well as lease financing. The Wealth Management segment consists of investment advisory services, retirement plan services, trust, municipal pension services and broker/dealer services. The Insurance segment consists of commercial lines, personal lines, benefits and human resources consulting.

Each segment generates revenue from a variety of products and services it provides. Examples of products and services provided for each reportable segment are indicated below.

Ÿ	The Banking segment provides financial services to consumer and commercial customers and governmental units. These services include a full range of banking services such as deposit taking, loan origination and servicing, mortgage banking, other general banking services and equipment lease financing.
Ÿ	The Wealth Management segment offers trust and investment advisory services, guardian and custodian of employee benefits and other trust and brokerage services, as well as a registered investment advisory managing private investment accounts for both individuals and institutions.
Ÿ	The Insurance segment includes a full-service insurance brokerage agency offering commercial property and casualty insurance, group life and health coverage, employee benefit solutions, personal insurance lines and human resources consulting.

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer

Revenue from Contracts with Customers

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)” and subsequent related updates. The Corporation adopted the guidance effective January 1, 2018 using the modified retrospective method though no adjustments were made to retained earnings as a result of the adoption. The Corporation’s revenue is the sum of net interest income and noninterest income. Revenues are recognized when obligations under the terms of contracts with customers are satisfied, including the transfer of control of the promised goods or services to customers, in an amount that reflects the consideration the Corporation expects to be entitled to in exchange for those goods or services. The Corporation provides services to customers which have related performance obligations that are completed to recognize revenue. The Corporation's revenues are generally recognized either immediately upon the completion of the services or over time as the services are performed. Any services performed over time generally require services to be rendered each period and therefore progress in completing these services is measured based upon the passage of time.

The following tables disaggregate the Corporation's revenue by major source for the three months ended March 31, 2018 and 2017.

Restructuring Charges

Restructuring Charges

During January 2018, the Corporation announced the closure of two owned financial centers and one leased financial center and reduced staff associated with these financial centers, resulting in accruing a loss of $571 thousand related to the Banking business segment. These financial centers were closed in April 2018. The remaining accrued restructuring expense at January 1, 2018 of $23 thousand relates to 2016 restructuring charges.

A roll-forward of the remaining accrued restructuring expense for the three months ended March 31, 2018 is as follows:

Accounting Policies [Abstract]

Principles of Consolidation and Basis of Presentation

Principles of Consolidation and Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of Univest Corporation of Pennsylvania (the Corporation or Univest) and its wholly owned subsidiaries. The Corporation’s direct subsidiary is Univest Bank and Trust Co. (the Bank). All significant intercompany balances and transactions have been eliminated in consolidation. The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations for interim financial information. The accompanying unaudited consolidated financial statements reflect all adjustments which are of a normal recurring nature and are, in the opinion of management, necessary for a fair presentation of the financial statements for the interim periods presented. Certain prior period amounts have been reclassified to conform to the current-year presentation. Operating results for the three-month period ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ended December 31, 2018 or for any other period. It is suggested that these unaudited consolidated financial statements be read in conjunction with the audited financial statements and the notes thereto included in the registrant’s Annual Report on Form 10-K for the year ended December 31, 2017, which was filed with the SEC on March 1, 2018.

Use of Estimates

Use of Estimates

The preparation of the unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include fair value measurement of investment securities available-for-sale, reserve for loan and lease losses and purchase accounting.

Recent Accounting Pronouncements

In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-02, "Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This ASUclarifies the accounting treatment of the reclassification of certain income tax effects within accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act. The Corporation elected to early adopt this guidance effective January 1, 2018 for all stranded tax effects resulting from tax reform and reclassified stranded tax effects, totaling $3.9 million, from accumulated other comprehensive income to retained earnings. The Corporation's policy for releasing income tax effects from accumulated other comprehensive income is to release such effects on an individual basis as each item is liquidated, sold or extinguished. See Note 10, "Accumulated Other Comprehensive (Loss) Income" for additional detail.

In March 2017, the FASB issued ASU No. 2017-07, "Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The amendments in this ASU require that an employer that sponsors defined benefit pension plans and other postretirement plans present the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. Other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The Corporation adopted this guidance effective January 1, 2018 with retrospective application for prior period presentation. Effective January 1, 2018, components of net benefit income other than the service cost component are presented in the Corporation's statement of income in other noninterest expense rather than in salaries, benefits and commission expense. Prior period components of net benefit income other than the service cost component were reclassed to other noninterest expense in the Corporation's statement of income.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." This ASU addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The ASU requires equity investments to be measured at fair value with changes in fair value recognized in net income. At December 31, 2017, the Corporation's equity portfolio had a carrying value of $1.1 million which included an unrealized net gain of $666 thousand. At December 31, 2017, $433 thousand was recorded in accumulated other comprehensive income which represented the unrealized net gain, net of income taxes, based on the Corporation’s statutory tax rate as of December 31, 2017. The Corporation adopted this guidance effective January 1, 2018 with a cumulative-effect adjustment to the balance sheet as of January 1, 2018. The balance in accumulated other comprehensive income of $433 thousand was reclassified to retained earnings effective January 1, 2018. The carrying value of the equity securities, at January 1, 2018, did not change; however, any future increases or decreases in fair value is recorded as an increase or decrease to the carrying value and recognized in other noninterest income. During the three months ended March 31, 2018, the Corporation recognized a $4 thousand net loss on equity securities in other noninterest income.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)” and subsequent related updates. The Corporation adopted the guidance effective January 1, 2018 using the modified retrospective method though no adjustments were made to retained earnings as a result of the adoption. The Corporation provided expanded disclosures related to recognition of revenue from contracts with customers. See Note 14, "Revenue from Contracts with Customers."

Recent Accounting Pronouncements Yet to Be Adopted

In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." The amendments in this update expand and refine hedge accounting for both non-financial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. Additional hedging strategies permitted for hedge accounting include: hedges of contractually-specified price components of commodity purchases or sales, hedges of the benchmark rate component of the contractual coupon cash flows of fixed-rate assets or liabilities, hedges of the portion of a closed portfolio of prepayable assets not expected to prepay, and partial-term hedges of fixed-rate assets or liabilities. The ASU amends the presentation and disclosure requirements and changes how entities assess effectiveness. The ASU eliminates the requirement to separately measure and report hedge ineffectiveness and requires all items that affect earnings be presented in the same income statement line as the hedged items. After initial qualification, the new guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test, such as a regression analysis, if the entity can reasonably support an expectation of high effectiveness throughout the term of the hedge. An initial quantitative test to establish that the hedge relationship is highly effective is still required. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for public business entities, or January 1, 2019 for the Corporation. Early adoption is permitted, including an interim period. The amended presentation and disclosure guidance is required only prospectively. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements.

In March 2017, the FASB issued ASU No. 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” This ASU shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, or January 1, 2019 for the Corporation. Early adoption is permitted, including an interim period. This ASU is to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This ASU eliminates Step 2 of the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the new guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, or for the Corporation's goodwill impairment test in 2020. Early adoption is permitted for goodwill impairment tests with measurement dates after January 1, 2017. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU requires businesses and other organizations to measure the current expected credit losses (CECL) on financial assets, such as loans, net investments in leases, certain debt securities, bond insurance and other receivables. The amendments affect entities holding financial assets and net investments in leases that are not accounted for at fair value through net income. Current GAAP requires an incurred loss methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. The amendments in this ASU replace the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonableness and supportable information to inform credit loss estimates. An entity should apply the amendments through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (modified-retrospective approach). Acquired credit impaired loans for which the guidance in Accounting Standards Codification (ASC) Topic 310-30 has been previously applied should prospectively apply the guidance in this ASU. A prospective transition approach is required for debt securities for which an other-than-temporary impairment has been recognized before the effective date. The ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those years for public business entities that are SEC filers, or January 1, 2020 for the Corporation. The Corporation is in the process of evaluating the impact of the adoption of this guidance on the Corporation's financial statements; however, it is anticipated that the allowance will increase upon adoption of CECL and that the increased allowance level will decrease shareholders' equity and regulatory capital and ratios.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" to revise the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases. Disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. The ASU is effective for the first interim period within annual periods beginning after December 15, 2018, or January 1, 2019, with early adoption permitted. The Corporation is in the process of evaluating the impact of the adoption of this guidance on the Corporation's financial statements; however, the adoption of this ASU will impact the balance sheet for the recording of assets and liabilities for operating leases; any initial or continued impact of the recording of assets will have a negative impact on all Corporation and Bank capital ratios under current regulatory guidance and possibly equity ratios.

Earnings Per Share, Basic and Diluted [Abstract]

Summary of Computation for Basic and Diluted Earnings per Share

The Corporation uses the two-class method to calculate earnings per share as the unvested restricted stock issued under the Corporation's equity incentive plans are participating shares with nonforfeitable rights to dividends. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the number of weighted average shares outstanding during the period. The table also notes anti-dilutive options which are those options with weighted average exercise prices in excess of the weighted average market value for the periods presented.

The following table sets forth the computation of basic and diluted earnings per share:

Amount of Securities in Unrealized Loss Position

The following table shows the fair value of securities that were in an unrealized loss position at March 31, 2018 and December 31, 2017 by the length of time those securities were in a continuous loss position. For the investment securities in an unrealized loss position, the Corporation has concluded, based on its analysis, that the unrealized losses are primarily caused by the movement of interest rates and current market conditions. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the par value of the investment. It is more likely than not that the Corporation will not be required to sell the investments before a recovery of carrying value.

At March 31, 2018, gross unrealized losses for securities in an unrealized loss position for twelve months or longer, totaled $12.0 million. Four federal agency bonds, thirteen investment grade corporate bonds, 105 federal agency residential mortgage securities, and seven investment grade municipal bonds had respective unrealized loss positions of $105 thousand, $6.7 million, $5.2 million and $51 thousand, respectively. The fair value of these 129 securities fluctuate with changes in market conditions which for these underlying securities is primarily due to changes in the interest rate environment. The Corporation does not intend to sell the securities in an unrealized loss position and is unlikely to be required to sell these securities before a recovery of fair value, which may be maturity. Upon review of the attributes of the individual securities, the Corporation concluded these securities were not other-than-temporarily impaired. The Corporation did not recognize any other-than-temporary impairment charges on debt securities for the three months ended March 31, 2018 and 2017.

In conjunction with the adoption of ASU 2016-01, the Corporation recognized a $4 thousand net loss on equity securities during the three months ended March 31, 2018 in other noninterest income and the net unrealized loss on equity securities held at March 31, 2018 was $4 thousand.
